UNITED vSTA'IES PATENT OFFICE ABNER M. WILLIAMS, OF OIL CITY,PENNSYLVANIA, ASSIGNOR OF ONE- HALF- HIS RIGHT TO CHARLES H. DUNCAN, OFSAME PLACE.

IMPROVEMENT I SUCKER-ROD JOINTS FOR PUMPS.

Specification forming part of Letters Patent No. 144,8 [3, datedNovember 18, 1873; application tiled October 15, 1873.

To all 'whom it may concern:

Be it known that I, A. M. WILLIAMs, of Oil City, in the county ofVenango, and in the State of Pennsylvania, have invented certain new anduseful Improvements in Sucker-Rod Joints for Pumps; and do herebydeclare that the following is a full, clear, and exact descriptionthereof, reference being had to the accompanying drawings and to theletters of reference marked thereon, making a part of thisspecification.

The nature of my invention consists in a socket wit-h screw-hole at thelower end, an interior shoulder, and four wings extending upward, toform a joint for sucker-rods for pumps, as will be hereinafter morefully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, in whichfFigure 1 is a side view, and Fig. 2 a longitudinal section, of myimproved sucker-rod joint.

i A represents a socket made of 1n alleable iron, with a screw-hole, B,at its lower end, and an interior circumferential shoulder, a, at thebottom ofthe socket. The upper end of the socket A forms four win gs, CC, which project upward in continuation of the socket, and haverivetholes through their upper ends to fasten to the rod. Heretoforethis class of joints have been made with two straps or wings, whichnecessitatedthe position of the rivets to run in a straight line withthe grain of the wood, thereby greatly tending to weaken and split thewood or rod to which the joint was riveted.

This has caused serious delay and inconvenience.

My invention overcomes this difficulty by the construction of the fourwings in combination with the socket. The wings C C run opposite oneanother, bracing the wood on one side while the rivets are being drivenon the other. The rivets, therefore, run transversely, and the socketholds the end of the wood so firm as to preclude any possibility of therod splitting. The end of the rod rests on .the interior shoulder a. Onthe inside ofthe wings C C, around the rivet-holes, are formed lugs b b,which are designed to take the strain off of the rivets on the upwardmotion, while the end of the rod which sits on the shoulder a in thesocket relieves the rivets on the downward motion.

I do not claim a clamp for sucker-rod joints consisting of two barsprovided with internal projections which fit into recesses in thesuckerrod.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

A sucker-rod joint consisting of the socket A, with interior shoulder aand the four eX- tended wings or straps C C C C, all formed of one pieceof metal, as and for the purposes herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand this19th day of July, 1873.
